Stegosaurus

Another famous existence that utilized two administrative centers was dinosaur.

To be specific, based on the fossil record, two classes of dinosaurs, the stegosaurus and the sauropods, are believed to have two brains.

The hypothesis roots from a distinctive finding: There is a large canal in the hip region of their spinal cord, which could actually accommodate over 10 times more neurons than their brain.

The reason of having a second brain near the back passage is simple - these creatures were just too big. You know what, stegosaurus could be as much as 12-meter long, and some species of sauropods were up to 40 meters. On the other hand, neuronal transmission does not become faster in a bigger animal.

The implication is: Bolt of Jamaica could chop off the foot of a sauropod and make an escape of 80 meters before the gigantic animal could feel the pain and start to think what's going on.

PS. Therefore, many so-called masterminds of some huge organizations are merely clusters of neurons near the asshole - you could learn that much by looking at (or smelling) their output.

PPS. When I first watched Dr. Slump (IQ博士) of Akira Toriyama (鳥山明), I used to laugh at King Nikochan (宇宙大王) for having his brain as the asshole. With time, I understand it was Toriyama's wisdom and profound knowledge on the anatomy of dinosaur and extra-terrestrials.
